yes that's what I'm asking ...
is there a reason why you are adding files with something other than CF but wanting to delete with CF?
and why not delete with whatever you are adding files with?
the key and secret key etc are needed to add files - so why not the same method?

See how one of the leading financial services organizations uses Recorded Future as part of a holistic threat intelligence program to promote security awareness and proactively and efficiently identify threats.

I should say that you aren't going to be able to simply send in a url and delete files.
You need to authenticate - otherwise anyone could delete your files. It's required that you send in your policy and signature and etc - and it needs to be hashed.
I posted you different articles that explain how to do this - the encryption as well.
This is why I asked how you were putting files to s3 - because it's similar.
You could login to your amazon s3 account and delete files manually as a secondary option.

However I'd like comment on your comment about paying EE to save time.
Have you ever researched what hiring a developer would cost - say for a couple hours - to help you with your issue?
And then have you compared that to what you pay EE?
Sometimes you get a full answer that tells you exactly what you need and sometimes you just get clues or ideas about your work.
How do you think the economics of having someone work on your problem for a couple hours would play out?
It would be at least as much and probably more than what I mentioned earlier about hiring a developer for a couple hours.
You are in fact getting a good deal paying such a low rate for membership.
If you are new to EE you'll see that in general you can quickly get the answers you are looking for.
